scripts/sorttable: Add helper functions for Elf_Shdr

In order to remove the double #include of sorttable.h for 64 and 32 bit
to create duplicate functions, add helper functions for Elf_Shdr.  This
will create a function pointer for each helper that will get assigned to
the appropriate function to handle either the 64bit or 32bit version.

This also moves the _r()/r() wrappers for the Elf_Shdr references that
handle endian and size differences between the different architectures,
into the helper function and out of the open code which is more error
prone.
